Formula
[(B - A) / A] x 100 A is the original number, and B is the new number Example: what is the percentage change from A to B? A = 150, B = 320
Subtract the new number with original number
B - A 320 - 150 = 170
Divide the first step number by the original number
170 / A 170 / 150 = 1.13
Multiply the second step number by 100
1.13 x 100 = 113
